VANET is a MANET subtype that enables multiple hop wireless systems without any need for established infrastructure. However, it requires an ad hoc routing algorithm for establishing communication among automobiles and Highway structures. NS3 is a simulation tool for the simulation of VANET. This type of simulation tool is used for simulating the VANET based applications and real-time scenarios with a different set of simulation configurations. Hence, in this article, we provide you with a complete picture of the VANET simulation in NS3.
While analyzing the quality of ad hoc routing protocols it would be far more time-consuming and cost-effective to install them in real-time situations on actual roads. Let us first start with VANET simulation classifications,
- NS3 is a GNU GPL – Licensed descript time and event simulator for computer systems
- It contains standards and routing methods ranging from physical to application layers
- Both riders and drivers will get benefit from the smart traveling and traffic updates from VANET
- In VANET, meanwhile, the communication node moves at a faster rate and has more processing power resources, such as memory, battery power, and CPU
What are the classifications of VANET simulators?
There are four categories in which the simulators are classified into different categories. We have provided a description and an example of them below.
- Category 1– one-way coupling
- Data network simulator is obtained as traffic traces and given to traffic simulator
- Category 2– two-way dynamic coupling (small scale and fixed interval)
- Interface between network and traffic simulator
- Example – SUMO Simulator and NS3 are used for simulation of car traffic flow based on transmitted and received packets
- Category 3– medium-scale two-way dynamic coupling (fixed interval)
- Using traffic and network simulator
- Example – VNS or Vehicular Network Simulator provides for integrating NS3 and DIVERT 2.0
- 11p standard of communication is supported by VNS
- Category 4– large scale two-way dynamic coupling (fixed interval)
- The communication analytical model is simulated using the traffic simulator
- Example – integration of OMNET ++ (Communication simulator) and SUMO (Traffic simulator) is present in this category
- TraCI interface that utilizes transmission control protocol connectivity for message sharing across the simulators
- TraCI provides for bidirectional coupling of these two simulators

Why separately use the NS3 module?
- We can opt to overlook items that exist theoretically among the particular events, focussing just on the separate periods when interesting things happen
- NS3 simulator is divided into modules each of which is constructed as an independent software library
- Every NS3 programs can connect the libraries they require to complete the simulation
Therefore NS3 is used extensively in the simulation of many projects especially vehicular ad hoc network systems, as we saw before; NS3 is specifically useful in the following aspects
- 3GPP New Radio (NR)
- NR and Vehicle – to – Anything (V2X)
- For deploying new technologies

- Bandwidth, numSubbands (total number of sub-bands), and subbandWidth (width of the sub-band in MHz)
- losCondition (conditions of the channel) and shadowing (fading)
- harqProcesses (Enable HARQ) and harqEnabled (UL and HL based HARQ)
- segmentDuration (2s for a segment) and segmentSizeFile (matrix (n,m))

So you can confidently depend on us for any kind of research assistance. We have dedicated sole teams for every aspect of research. Now let us look into the performance metrics used in the evaluation of VANET systems.
Performance Metrics for VANET
The influence of propagation models on network performance is measured using the metrics below.
- Throughput– Ratio between the maximum amount of bytes received at the endpoint and the complete simulation duration
- Latency– the summation of all the end-to-end delay taken for those packets received (calculated over the entire data)
- Receive time– the time spent and acquiring packets is aggregated across 1000 millisecond window and is normalized throughout the complete simulation period
- Packet Loss Rate– the ratio of transmitted data packets to the number of packets missed by those anticipated one-hop receivers (all vehicles inside a transmission vehicle’s broadcast range)
- Jitter– the discrepancy between the latencies of two successive packets
On all of the above parameters, all of our projects yielded the best results. We provide research assistance on a wide range of NS3 issues.
